Is this ad interesting enough?

[POWNED]

In my school we have this student coaching, where students who are the best in certain subjects can teach it to other student. Usually the fees are around 20-40$ per hour. And you can coach the students in need of help whenever you don't have a class at school. I plan on coaching math and biology.
Here goes nothing :

"Math and Biology Coaching
Need help in math and biology? I could help out My time is flexible after 3pm. My fee is 10$/45min. Interested? You can reach me at (EMAIL) or SMS me at (NUMBER). "

Instead of repeating the same concept:
Math and Biology Coaching
Need help in math and biology
You might mention the goal: "up your exam scores", "get homework done quicker"

A different ad each week could mention the current curriculum topic that trips everyone up.
